25 to cooperate withA a companion fixed will be explained hereinafter, these two sections of the front axle are maintained always in horizontal alinement so that the front axle as a whole may be turned bodily for 5 steering purposes, as will be explained.

The casing 15 -of the rear differential mechanism is preferably provided with a y hollow lug 22 which terminates in an annular iange 23. To this flange 23 there is bolted or otherwise secured the casing of an electric motor 24 whose operating shaft 25.

projects through the flange 23, the lug 22 and into4 the casing 15 of the rear differential mechanism. l` shaft 25-which projects into thel casing is 'provided with a worm gear 26 adapted to mesh with the aforesaid gear 16 of the rear differential mechanism so as to drive-the ceive the bearing balls 3l designed to reduce friction .and thereby facilitate 'rotation oli the rotatable part of the lifth wheel and conv sequently enable easy and free turning of the front axle and the wheels carried thereby. 'v

Projecting upwardly from the upper face of the rotatable partv28 of the iii'tn wheel.

and projecting through the ixed fifth wheel member 29 is a support 33 to which is bolted or otherwise secured an electric motor 32. The lower end of the, drive shaft 34 ofthis front electric motor 32 extends loosely through said support 33 and through the fth wheel'and hollow lug 27 into the casing .'20 andat its endv which projects into a f the casing 2O` it is provided with a .worm

gear 35 ada ted to mesh with the aforesaid gear21 of t e front 'differential mechanism for the purpose of driving the ,front wheels. Itwill thus be seen that .I provide two electric motors, one for driving the front wheels and one for driving the rear wheels.`

- The four ground wheels of the vehicle are therefore driven with equal power and it j' will be understood that the' electric motors used for this'purpose may. be of any "de-- sited vsize'and of any, well known type and rovided with the 4necessary appurtenances 6o or the 'performance` of the functions outlined for them.

To drive'the electric motors 24 and 32 any suitable engine may be employed. I',

prefer to use a gas' engine of the two, four or six' cylinder variety. Thi@ gas engine is hat end of said motor. 15.

,'manner. This-controlling mechanism may to establish lelectrical communication be indicated at 36 and is illustrated as of the four cylinder type. To its crank shaft I couple up with it in any suitable manner an electric generator 37 havin all ofthe .lappurtenances necessary for t e generation of m electricity incident tooperation ofy the en. j gine. The4 engine may be started in anyV suitable manner, as for'instance, by hand or a self-startingcontrivance. The operation of the gas or.- other engine 36 operatesthe 75 generator 37 'to generate electricity for .supply to the electric motors 24 and 32 to operate the motors and thereby drive the wheels of the vehicle to propel the latter.l

The generator'employed by me ma be of a@V any desired type and of` any "suitab e` size. It may be connected upv with `the front and rear motors through the instrumentality of` anysuita-ble electrical connetior'is or. appunti tenances capable of establishing proper elec- 35 trical connection between it and the motors. n As shown in the accompanying drawings, the generatoris connected*l up to the rear motor by means of the wires 38, l39 and 40. The wires 39 and 40 preferably extend up go through the hollow-steering post 41 and are connected in any well known manner to the steering wheel 43 and the controlling lever 42 on the steering wheel. l .The front electric motor 32, as shown in g5 the accompanying drawings, maybe connected up with the generator 37. by means ofthe wires'44, 45 and 46. The wires-45 and 46 .preferably extend up through the hollow steering post 41 for' connection with the steering wheel and the controlling lever 47. v'lhese'controlling levers 42 and 47 are preferably arranged onelon top of the other but they may'be `arranged-in any suitable be of any well .known type with the levers coperating with terminals 48. and 49 on the steering wheel for the purposeof connecting the wires 39 and 40 and 45 and 46 110 tween the generator and the respective mo-:

tors.' Therefore, one motor at a time may be connected electrically with the generator 37, orV bothv may be connected ywith the generato'relectrically at the s ame time, as may 115 be desired, and by virtue of the controlling mechanism being ofcommon type, the contr, lof the motor should be 'readily under stood.

h The chassis at'the rear. is. supported onlizo two points by the aforesaid two side springs 12 and 12. `At the front of thevehicle the chassis preferably has one point of suspeirifv sion. For instance, two side springs t may be connected 'to the .side sills of the chassis. 125

Intermediate the ends of these side springs t there may be connected---tliie` ends of a trans verse spring u which is; referably pirated intermediate its ends on tillug 'v an the non-rotatable part of the fifth wheeled the 13e 'los , casing and operatively connected to the rethe hollow lug of the front casing forming /part of said fifth wheel, a reach bar having ,spective differential mechanism, and means for driving said motors.

4. In a motor vehicle, a chassis, front and rear axles, a differential mechanism connected to each axle, a casing for the front ldiiierential mechanism which has a hollow lug provided with anannular'liange, a ifth wheel interposed between the dilferential mechanism casing of the frontaxle and the body of the vehicle,the aforesaid flange of connection with the rear axle and at its front end having connection with the fifth wheel and with the front differential mechanismV casing, and means for driving the differential mechanisms. e

5. In a motor vehicle, a chassis, front andV nected to each axle, a casing J@or euch difer- Y ential mechanism, an electric motor connected to and supported hy each casing, a fifth wheel interposed between the front differential mechanism casing'and the front [electric lmotor,` springs connected to the chassis at the front end thereof, and a transversely disposed spring havin connection with said wheel and also with t e rst-mentioned springs.

Ina motor vehicle, a chassis, an axle, ground wheels carried by the axle, a diil'er ential mechanism on the axle, a casing for the differential mechanism, a motor supported on the differential mechanism casing and free of direct connection with the chassis, and provided with a vertically disposed drive shaft which extends within said casing, and a worm gear en the lower end of said shaft in mesh with the diiierential mechanism.

8. In a motor vehicle, anaxle, a differential mechanism connected to the axle, a casingv for the 'differential mechanism provided with an outwardly extending hollow projection located above the plane of the axle, a motor connected to the -hollow projection and su ported solelyby its connection with the hollow projection of the casin and provided with a 1drive shaft whic extends through said hollow projection into the casing, and an operative 'connection 'between the drive shaft and the differential mechamsm.
